WILLIAM BAYLEY, OF SPRINGFIELD, OHIO.

WINDOW-SASH ADJUSTER.

Patented Apr. 11st, 18*141. Application filed August 4, 1913. Serial No.782,858.

393399, Specification of Letters Patent.

To auto/10m it may concern Be it known that I, VVILLIAM BAYLEY, citizenof the United States, residing at Springfield, in the county of Clarkand State of Ohio, have invented certain new and useful Improvements inWVindow-Sash :kCljHStGIS, of which the following is a specification.

My invention relates to adjustable window constructions embodyingmovable sashes and particularly to an adjuster adapted to shift themovable sash uniformly through out its entire length during its openingand closing movement.

lVhile the invention has been herein shown and described in connectionwith a particular type of balanced window sash it is to be understoodthat it is equally applicable to sashes hinged to oscillate about eithera vertical or horizontal axis located either at the edge of the sash orupon a medial line, or it might be adapted to operate a sliding sash.

The object of the invention is to simplify the structure as well as themeans and mode of operation of such devices, whereby they will not onlybe cheapened in construction but will be more efficient in use, uniformin operation, easily and quickly manipulated to adjust the sash to thedesired position, c0mpact in form requiring a minimum operating spaceand unlikely to get out of repair.

A further object of the invention is to provide a device which willafford a multiplication of power, whereby a window sash of large extentand greatweight may be adjusted with minimum expenditure of energy.

lVith the above primary and other incidental objects in view as willmore fully appear in the specification, the invention consists of thefeatures of construction, the parts and combinations thereof and themode of operation or their equivalents as hereinafter described and setforth in the claims.

Referring to the drawings, Figure 1 is a perspective view of theassembled apparatus and a portion of window sash with which theapparatus is connected, the sash being shown in its open position. Fig.2 is a sectional end elevation of the window sash and adjuster. Fig. 3is a plan view of the adjuster and sash, Fig. 1 is a detail side elevation, Fig. 5 is a detail view of the adjusting wheel.

Like parts are indicated by similar chara floating acters of referencethroughout the several views.

The apparatus forming the subject matter hereof is particularly designedfor use in factory buildings, auditoriums or wareiouse constructions,wherein are employed movable window sash of large area and of greatweight. The apparatus may likewise be employed in conjunction withsashes of small size, such as are used in ofiices, stores andresidences, or for operating the ventilators of railway cars. Theadjuster is especially adapted for use in conjunction with movable sashcomprising single units of extreme length. It is capable of operating asash having a length of several hundred feet uniformly throughout itsentire extent.

In the drawings 1 and 2 frame members of the building structure,comprising the cap and sill respectively of the window opening. Themovable sash 3 is suspended upon the swinging links t pivoted 5 to thebracket 6 secured to the building structure and at their lower ends,pivotally engaged at 7 with the sash 3 adjacent to the lower edgethereof. Other links 8 pivoted at 9 to the brackets 6 are pivotallyconnect ed at 10 adjacent to the upper edge of the sash. The relation ofthe links 1 and 8 and their pivotal connections aresuch that the sash 3will travel through a simultaneous oscillatory and shifting movement inwhich the center of gravity will travel in a horizontal plane, while thesash oscillates about axis coincident with the center of gravity. Thisparticular window construction and method of supporting and guiding thesash 3 is fully described in my co-pending application, Serial No. 777,6341, and forms no part of the present invention.

The adjuster apparatus forming the subject matter hereof, comprises afloating shaft or rod 11, having therein a screw threaded section 12.The screw threaded section 12 may form an intermediate portion of theshaft or rod 11, or may be located at either end thereof. While thesection 12 may be formed integral with the shaft or rod 11, it ispreferably a separate member connected with the shaft 11 by suitableunions or conplings 13. The floating shaft or rod 11 is arrangedparallel with a stationary supporting member, which in the presentinstance is the structural bar 2 forming the are longitudinal sill ofthe window opening. The shaft or red 11 is supported throughout ashifting parallel movement by means of a plurality of parallel swingingoperating levers 14. These operating levers 11 are preferably though notnecessarily of a bifurcated'formation, whereby the inner arms 15 of thelever will be double, the parallel portions of which are separatedbyintermediate space blocks 16. These operating levers are pivotallysupported upon the longitudinal stationary supporting bar which asbefore stated, is the window sill 2. V

The extremities of the inner arms 15 of the operating levers 1-1, arepivotally connected with the bearing sleeves 17 on the shaft 11,carrying trunnions 18 with which the parallel portions of the arms 15are engaged. The bearing sleeves 17 are preferably though notnecessarily, longitudinally adjustable upon the shaft 11, and aresecured in adjusted positions by set screws 19. The adjustment of thebearing blocks 17 facilitates the assembling of the apparatus and itsinitial adjustment.

If found desirable, swinging arms 20, corresponding to the arms 15 ofthe operating levers lt, may be located intermediate the said levers 14and pivotally connected with the sill 2 and the shaft 11 in the mannerbefore described. It is obvious that a longitudinal shifting movement ofthe shaft or red 11, will cause a simultaneous oscillation of theoperating levers 14 and the swinging arms 20 in unison one with theother. It is obvious that in addition to the longitudinal movement ofthe shaft or rod 11, there will be a limited lateral movement thereofdue to the arcuate pat-h of the pivotal connections 18 of the arms 15and 20 with the shaft 1 about their pivotal connection with thestationary support 2. Links 21 pivotally connected with the extremitiesof the operating levers 14L and with the movable sash 8, cause theoperating levers lt to move the sash simultaneously with thelongitudinal movement of the shaft 11.

It is to be noted that while the shaft 11 is capable of a longitudinalmovement and a limited lateral movement in unison with the oscillationof the operating levers 1a and swinging arms 20, it is securely heldagainst rotation by the engagement of the bearing blocks or sleeves 17therewith.

Screw threaded upon the threaded section 12 of the shaft 11 is arevoluble adjusting nut in the form of a wheel or pulley 22. While thewheel or pulley 22 is capable of revoluble movement, it is held securelyagainst lateral movement upon the screw threaded section 12, whereby arotation of the wheel or pulley 22 will cause the screw threaded section12 of the shaft which is held against rotation, to travel through thewheel, thereby moving the shaft or red 11 longitudinally to cause asimultaneous oscillation of the several operating levers 14. 'To securethe wheel or pulley 22 against lateral movement while permitting therevoluble movement thereof, there is provided upon the wheel a laterallyprojecting hub 23, having therein a peripheral groove. Located in theperipheral groove of the hub 23, is a collar or boxing 24, with which ispivotally engaged the extremity of a swinging arm 25 pivoted to thestationary support 2. The

swinging arm 25 is preferably though. not

necessarily formed double and comprises two parallel bars spaced apartby intermediate space blocks 26. The parallel portions of the arm 25 arepivotally connected with the collar or boxing 241 at diametrically0pposite points. The constructionis such that the swinging arm mayoscillate to and fro to compensate for the lateral shifting move ment ofthe shaft 11, due to the arcuate paths of the supporting arms 15 and 20,while at the same time it will limit the lat eral movement of the wheelor pulley 22 in line with the shaft. The wheel 22 freely rotates withinthe collar or boxing 24:. To further support the floating shaft 11 andpulley 22, and to relieve the arms 15 and 20 whereby said arms mayoscillate freely, the shaft is further supported by auxiliary suspensionlinks 27 flexibly connected with the shaft or swinging arms and with thebuilding structure, as shown at 28 and 29 respec tively, in Fig. 2. InFig. 2 the uppermost trunnion of the collar or box is shown providedwith a thimble 30, with which the link 27 is engaged. It is obvious thatother forms of connector may be used in lieu thereof. While the path ofthe connection 28 will be slightly arcuate, concentric with theconnection 29, such variation will be so slight as to be immaterial andwill befully compensated for by the play of looseness of bearings whichwould naturally result in structure of this character.

The adjuster thus described may be 10-- cated at any height inaccordance with the window sash to be operated and may be controlledfrom a lower level by means of a cable 31 passing over the wheel orpulley 22, whereby said pulley may be rotated to cause the longitudinaladjustment of the shaft 11 to oscillate the levers 1 1. Y

It is obvious that without otherwise appearance would not be dilterentfrom that now shown.

From the above description it will be apparent that there is thusprovided a device of the character described, possessing the particularfeatures of advantage before enumerated as desirable but which obviouslyis susceptible of modification in its form, proportion, detailconstruction or arrangement of parts, without departing from theprinciple involved or sacrificing any of its advantages.

IVhile in order to comply with the statute, the invention has beendescribed in language more or less specific as to certain structuralfeatures, it is to be understood that the invention is not limited toany specific details, but that the means and construction hereindescribed comprise but one mode of putting the invention into efiiect,and the invention is therefore claimed broadly in any of its possibleforms or modifications within the scope of the appended claims.
